Try solving the following puzzle before looking at the solution!Missing Dollar PuzzleCan you figure out what happened to the missing dollar?For reference, I have included the text of the puzzle below as well as in the image.Three people go to a hotel to stay the night, they ask how much to the person at the desk. The person at the desk says $10 each ($30). They hand over $10 each ($30) and go to the room. The person at the desk thinks they charged too much so they give the bellhop five $1 bills ($5) to give to the three people. On the way, the bellhop puts $2 in their pocket. The bellhop gives the people $3 back. Now they each paid $9 each not $10. Simple arithmetic, 3X9=27. The Bellhop kept $2, so 27+2=29.What happened to the other dollar?Source:SolutionThe puzzle asks to find the missing dollar, but is there actually a missing dollar? To understand what is going on, we can make a breakdown of the transactions:The three customers give the hotel $30. The hotel gives the bellhop $5. The bellhop gives the customers $3.This means that the three customers paid $27 total. The bellhop received $2 total and the hotel received $25 total. The total paid is $27 and the total received is $27. So, everything checks out and there is no missing dollar!The puzzle involved an incorrect addition, namely $27 + $2 = $29. $27 is the total amount paid by the customers and $2 is the total amount received by the bellhop. There is no reason to add these numbers! And there is no missing dollar!Source:New Puzzle: Find the Hidden 8How fast can you find the hidden 8?Source: [

▶️ In #MESExperiments 38 I show that stirring a column of water causes an egg to rise 33% faster and fall 25% slower than a ping pong ball, thus confirming Viktor Schauberger's rising egg experiment. Viktor Schauberger was an Austrian forester, inventor, and scientist that maintained the unique perspective that water was a living entity and prefers to move in a vortex manner. From this perspective, he stated that a shape that allows water to flow as a vortex around it would be able to move through water much easier than other shapes, such as a sphere. Viktor demonstrated this by his rising egg experiment, which involves stirring a column of water causing an egg to rise faster than a ping-pong ball filled with saline water to have the same buoyancy as the egg.In order to validate his rising egg experiment properly, I used a plastic egg that was similar in size to a ping pong ball and filled them both with salt water until they sunk freely downwards. Then I performed the rising experiment 10 times each for the ping pong ball, the egg with broad side down, and the egg with broad side up. I timed the total time, and then I timed the rising only and falling only times. I did the experiment many times to minimize the influence of any variables such as stirring speed, water rotation rate, or position of the egg/ball in the cylinder.At the start the egg fell faster than the ball indicating it was a bit more buoyant but, due to the water being in constant rotation after stirring, the egg with the broadside up fell 25% slower than the ping pong ball. In total, the egg with the broadside up rose 33% faster than the ping pong ball, while the egg with the broadside down still rose 18% faster than the PPB. Pretty amazi
